Figure 2: (A) The sections of the specimen showed a picture of corneal tissue with marked thinning epithelium and focal absence of Bowman's layer (arrow) and aggregation of lymphocytes composed of both B-cells and T-cells and neutrophils in the subepithelial tissue (arrowheads). (B) The sections of the limbal tissue specimen exhibited the presence of moderate lymphocyte infiltration (arrow) composed of both T-cells and B-cells with CD3 immunostaining [in (C), arrow] and CD20 immunostaining [in (D), arrow], fibrosis, and neovascularization (arrowhead) in the subepithelial tissue. (E) The immunohistochemistry stain of cornea reveals the presence of CK13-positive squamous epithelium (arrow) overlying corneal stroma. (A: H&E 200×; B: H&E 100×; E: 100×). CK13 = cytokeratin 13; H&E = hematoxylin and eosin.
